An introductory interactive describing the various work being done at LNL
This investigation is a lab where students find out if mass is created or destroyed in a closed system. Students will balance the chemical equation to re-enforce their findings.
This investigation is to help reinforce the idea that a mixture can be taken apart by physical means. It will be set up as a contest in which students will have 3 hours of class to separate as much pure substance as they can. These will be broken into percentages based on purity and the amount they have been able to separate. There is no procedure written so students have a completely open and inquiry based activity.
In this video from the Encyclopedia of Physics Demonstrations, observe how a laser beam is trapped in a water jet because the light reflects against the surface of the water.
Learn about the elements used to create the spectacular colors seen in firework celebrations. Color your own firecracker, then use paper and a straw to design a system to launch your firework.
In this video segment adapted from NOVA, scientist Mike Garcia draws lava samples at the foot of the active Kilauea volcano to see if it is related to its neighboring volcano, Mauna Loa.
This activity can be used to teach concepts how different densities of liquids can be layered and/or how the salinity of water affects the movement of ocean water.
This activity is a whole group guided inquiry activity/lecture where students will learn what dimensional analysis is, how to use dimensional analysis and learn more about why it is so important. It will provide the foundation for moving into stoichiometry.
Students wear nametags of an ion and find others throughout the school with whom they can create ionic compounds.
In this video segment adapted from NOVA, a team of archaeologists and engineers explores different uses of the lever by recreating the engineering feats of the ancient Easter Island peoples.
How can you lift a heavy metal table using air? In this video segment adapted from ZOOM, cast members succeed in lifting a table using their own breath and a few plastic bags.
This video segment adapted from Shedding Light on Science describes how astronomical distances can be measured in units of light-years, and how the finite speed of light allows astronomers to study how the universe looked long ago.
This video segment adapted from Shedding Light on Science demonstrates the law of reflection by showing how light energy is reflected off both smooth and rough surfaces at predictable angles.
An exercise in which students apply limiting reactants, mass ratios and percent yields to suggest an optimum industrial process. Cost figures are provided but students are told to come up with, and defend, their own criteria for their recommendation.
This video segment of Swift: Eyes through Time provides concrete examples to explain the concept that distance in space equals distance in time.
Loopy dot diagrams uses fruit loops as a manipulative to help students develop the basic skills for making Lewis dot structures to model covalent bonding.
A visual representation of superconductivity
A short activity using goldenrod copy paper as an indicator to introduce neutralization reactions. Students describe what they beleive happens during this reaction.
Students measure the relative intensity of a magnetic field as a function of distance. They place a permanent magnet selected distances from a compass, measure the deflection, and use the gathered data to compute the relative magnetic field strength. Based on their findings, students create mathematical models and use the models to calculate the field strength at the edge of the magnet. They use the periodic table to predict magnetism. Finally, students create posters to communicate the details their findings. This activity guides students to think more deeply about magnetism and the modeling of fields while practicing data collection and analysis. An equations handout and two grading rubrics are provided.
Have you ever wished your drawings would come alive and the stick figures or objects on your paper could move around? What sounds impossible is actually not! In this activity, you will make your drawing more around be letting it float on water. What makes this possible is the interesting chemistry of dry erase markers.
